Currently on month three of side effects. LIghtheadedness, head pressure and tingling, feeling like I am going to pass out, awful Castro pain, gas, belching, chest pain. Tendinitis in both knees and left wrist with swelling. Weak, tired, sick 80% of the time. I have been scoped, had mid section ultrasound, heart stress test, numerous EKGs, blood workups, all within range except for low potassium. This is poison and it just goes on and on. Most Doctors are skeptical although I have found two that believe this is a result of Levaquin, after seeing a half dozen including my internist, Gastro Doctor, urgent care Doctor, ER Doctors, cardiologist, etc. I would think the insurance companies would want this off the market. My medical bills are out of sight and my deductible which is rather large was met two months ago.
